magic file to klayout for SKY130

Hi,

I have tried to transfer a SKY130 magic file .mag to KLayout. It can be read, but the GDS numbers are not OK, only the layer names even if I use the layer mapping such as (also attached) :
NWELL:64/20
DIFF:65/20
TAP:65/44
DNWELL:64/18

What is the proper method to read a SKY130 mag file with KLayout ? Maybe the mapping is sensitive to layer name case ?

Thank you, BRgds,
Laurent

    Hi Laurent,

    I just tried to reproduce the issue, but it seems to work for me:

    # With test data from klayout sources:
strm2gds --layer-map-file=map.txt testdata/magic/gf180mcu_ocd_sram_test/gf180mcu_ocd_sram_top.mag.gz test.gds

    with "map.txt":

    metal1:100/0
via1:101/0
metal2:102/0
via2:103/0
metal3:104/0
via3:105/0
metal4:106/0
via4:107/0
metal5:108/0
glass:10/0
isosubstrate:11/0
psubdiff:12/0
fillblock:1/0

    gives me a GDS file with the layers mapped.

    However, I found a problem when the map is not fully specified - i.e. some layers are in the Magic file that are not mapped - in that case, KLayout stalls (https://github.com/KLayout/klayout/issues/2438).

    In general, Tim advises against KLayout, since Magic does some magic translating vias and for other reasons. So the recommended method is to use Magic to convert to GDS.

    Best regards,

    Matthias

    Hi Matthias,

    Indeed, I have installed and used magic command : gds write output.gds
    And my goal was to check if I can get the same result from a KLayout import mag file, because magic is only on linux, not on windows.

    BRgds,
    Laurent
